The brunette is still reeling from the backlash over her affair with married director Rupert Sanders and her breakup with Robert Pattinson.
Instead she will wait until next month's Toronto Film Festival which she is scheduled to attend to make her first public appearance.
"Kristen has been hiding ever since the story of her affair with Rupert broke – and she doesn't plan on breaking that habit just yet," a source close to the actress told the site.
"Unlike Rob, who faced the music and threw himself into promoting his new movie Cosmopolis, Kristen isn't comfortable with facing a barrage of questions about the cheating scandal.
"Her pals have urged her to follow Robert's lead and do some interviews for On The Road – just to get it over and done with. The sooner she faces the music, the quicker it will all end and the media glare will fall on someone else.
"However, Kristen is scared. The backlash from her Twilight fans has upset her – she's lost and doesn't know what to do.
"The longer she stays out of the spotlight, the worse she looks. This could have been over if she stood up to her problems and apologized for her actions in an exclusive interview."
Robert, 26, has appeared on a few shows to promote his new film but has awkwardly skirted around actually addressing the issue.
